Two American citizens have been placed under quarantine in mainland China over swine flu fears, CBS News reports. Another two have been held and released, according to a US Embassy spokeswoman who said the Americans were detained either because they showed flu-like symptoms or were close to "cases of interest to the Chinese authorities."
China has also quarantined 29 Canadians and 71 Mexicans. A plane sent by the Mexican government—which complains its citizens, including a diplomat, have been unfairly singled out—arrived in China today to take them home. "There are soldiers who won't let us go past the gate," said one Mexican woman being held in a Beijing hotel. "This is like a kidnapping for us." (More China stories.)
